Rollup merge of rust-lang#102495 - nnethercote:reinstate-hir-stats, r…

Reinstate `hir-stats.rs` test for stage 1.

It was disabled in rust-lang#94075 for stage 1 because that PR changed type layouts such that the results for this test were different for stage 1 and stage 2. But now that rust-lang#94075 is in beta, the results for this test are now the same for stage 1 and stage 2.
